Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AD8055ARTZ-R2 are selected based on strict electrical and mechanical compatibility criteria. All substitute candidates must meet the following requirements:

Mandatory Compatibility Parameters:

• Amplifier Type: Voltage Feedback
• Number of Circuits: 1
• Package / Case: SC-74A, SOT-753 (SOT-23-5)
• Mounting Type: Surface Mount
• Operating Temperature Range: Minimum -40°C, Maximum ≥125°C or compatible with application requirements
• Voltage Supply Span: Minimum ≤8 V, Maximum ≥12 V

Electrical Performance Considerations: Substitute parts are grouped based on their ability to operate within the supply voltage range of 8 V to 12 V and maintain functional equivalence in voltage feedback amplifier applications. Parts with slew rates, bandwidth, and output current capabilities within the operational envelope of the original device are considered direct substitutes.

The following substitute parts meet the mandatory compatibility criteria:

• LMH6654MF/NOPB and LMH6654MFX/NOPB (Texas Instruments)
• OPA820IDBVR and OPA820IDBVT (Texas Instruments)
• OPA830IDBVR and OPA830IDBVT (Texas Instruments)

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute Candidates:

OPA820IDBVR and OPA820IDBVT are the preferred substitutes for the AD8055ARTZ-R2 in applications requiring high-speed voltage feedback amplification. Both variants offer superior -3dB bandwidth (800 MHz) and gain bandwidth product (280 MHz) compared to the original device, with slew rate of 240 V/µs. These parts are manufactured by Texas Instruments, carry ROHS3 compliance, and are available in Active product status. The OPA820IDBVR is available in Cut Tape & Digi-Reel packaging with 22,300 units in stock, while OPA820IDBVT is available in Tape & Reel packaging with 1,274 units in stock. Both operate within the 5 V to 12 V supply range and maintain the SOT-23-5 package specification.

Secondary Substitute Candidates:

LMH6654MF/NOPB and LMH6654MFX/NOPB are suitable substitutes for applications where lower slew rate (200 V/µs) and reduced bandwidth (260 MHz gain bandwidth product) are acceptable. These Texas Instruments devices offer higher output current capability (120 mA) and lower input offset voltage (1 mV). Both are ROHS3 compliant with Active product status. LMH6654MF/NOPB has 2,200 units in stock, while LMH6654MFX/NOPB has 1,566 units in stock. These parts operate within the 4.5 V to 12 V supply range, providing broader supply voltage compatibility than the original device.

OPA830IDBVR and OPA830IDBVT are alternative substitutes offering the highest slew rate (600 V/µs) among available options, with -3dB bandwidth of 310 MHz. OPA830IDBVR is in Active status with 35,400 units in stock, while OPA830IDBVT is in Last Time Buy status with 2,330 units in stock. Both are ROHS3 compliant. These parts operate within the 2.8 V to 11 V supply range. OPA830IDBVT should be avoided for new designs due to Last Time Buy status.

Operating Temperature Consideration:

The AD8055ARTZ-R2 operates to 125°C maximum, while all substitute parts operate to 85°C maximum. Applications requiring operation above 85°C cannot use these substitutes without design modification or thermal management review.

Compliance and Availability:

All substitute parts carry REACH Unaffected status and EAR99 ECCN classification, matching the original device. All are ROHS3 compliant. OPA820IDBVR offers the highest inventory availability (22,300 units) and Active product status, making it the most reliable long-term substitute choice.

Frequently Asked Questions (FAQ)

Q: Can the OPA820IDBVR directly replace the AD8055ARTZ-R2 without circuit modification?

A: The OPA820IDBVR is pin-compatible and functionally equivalent in SOT-23-5 packaging. Both are single-circuit voltage feedback amplifiers with identical pinout. Direct PCB substitution is possible. However, the OPA820IDBVR operates to 85°C maximum versus 125°C for the AD8055ARTZ-R2. Applications operating above 85°C require thermal management review or alternative component selection.

Q: What is the difference between OPA820IDBVR and OPA820IDBVT?

A: Both parts are electrically identical with identical electrical specifications. The difference is packaging format: OPA820IDBVR is supplied in Cut Tape & Digi-Reel format, while OPA820IDBVT is supplied in Tape & Reel format. OPA820IDBVR has significantly higher inventory availability (22,300 units versus 1,274 units). Selection depends on procurement and assembly requirements.

Q: Why do the LMH6654 variants have lower slew rate than the AD8055ARTZ-R2?

A: The LMH6654MF/NOPB and LMH6654MFX/NOPB are designed for different performance characteristics. While they offer lower slew rate (200 V/µs versus 1400 V/µs), they provide higher output current capability (120 mA versus 60 mA) and lower input offset voltage (1 mV versus 3 mV). These parts are suitable for applications prioritizing output drive capability and precision over maximum slew rate.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed (LMH6654MF/NOPB, LMH6654MFX/NOPB, OPA820IDBVR, OPA820IDBVT, OPA830IDBVR, OPA830IDBVT) carry ROHS3 compliance certification. The original AD8055ARTZ-R2 does not specify RoHS status in the provided data.

Q: What is the significance of Moisture Sensitivity Level (MSL) differences?

A: The AD8055ARTZ-R2 carries MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. Substitute parts OPA820IDBVR, OPA820IDBVT, OPA830IDBVR, and OPA830IDBVT carry MSL 2 (1 Year), requiring storage in controlled humidity environments and baking before reflow soldering if exposed to moisture. LMH6654MF/NOPB and LMH6654MFX/NOPB carry MSL 1 (Unlimited), matching the original device's moisture handling requirements.

Q: Can I use OPA830IDBVT for new designs?

A: OPA830IDBVT carries Last Time Buy product status, indicating the manufacturer is discontinuing this part. While currently available (2,330 units in stock), new designs should use OPA830IDBVR (Active status, 35,400 units in stock) or alternative substitutes to ensure long-term supply availability.

Q: What supply voltage range is compatible with all substitute parts?

A: The AD8055ARTZ-R2 requires 8 V to 12 V supply. All substitute parts operate within this range: LMH6654 variants operate 4.5 V to 12 V, OPA820 variants operate 5 V to 12 V, and OPA830 variants operate 2.8 V to 11 V. For designs using the full 8 V to 12 V range, all substitutes are compatible.

Q: Are there any differences in REACH or ECCN compliance?

A: All parts listed carry identical REACH Unaffected status and EAR99 ECCN classification, matching the original AD8055ARTZ-R2. No compliance differences exist among the substitute options.
